Gaia DR2 giants in the Galactic dust -- II. Application of the reddening maps and models
George Gontcharov, Aleksandr Mosenkov
We exploit a complete sample of 101\,810 {\it Gaia} DR2 giants, selected in Paper I in the space cylinder with a radius of 700 pc around the Sun and a height of pc, usin…
{\it Gaia} DR2 giants in the Galactic dust -- I. Reddening across the whole dust layer and some properties of the giant clump
George A. Gontcharov, Aleksandr V. Mosenkov
We consider a complete sample of 101810 giants with Gaia DR2 parallaxes within the red clump domain of the Hertzsprung-Russell diagram in the space cylinder with a radius…
The dual nature of blazar fast variability. Space and ground observations of S5 0716+714
C. M. Raiteri, M. Villata, D. Carosati +39
Blazar S5 0716+714 is well-known for its short-term variability, down to intra-day time-scales. We here present the 2-min cadence optical light curve obtained by the TESS space tel…
Kinematic Properties of Young Intermediate- and Low-Mass Stars from the Gaia DR2 Catalogue
V. V. Bobylev, A. T. Bajkova
We have studied the kinematic properties of young pre-main-sequence stars. We have selected these stars based on data from the Gaia DR2 catalogue by invoking a number of photometri…
The intensity and evolution of the extreme storms in January 1938
Hisashi Hayakawa, Kentaro Hattori, Alexei A. Pevtsov +7
Major solar eruptions occasionally direct interplanetary coronal mass ejections (ICMEs) to Earth and cause significant geomagnetic storms and low-latitude aurorae. While single ext…
Effect of increased stability of peptide-based coatings in the Casimir regime via nanoparticle doping
G. L. Klimchitskaya, V. M. Mostepanenko, E. N. Velichko
We find that thin peptide films and coatings doped with metallic nanoparticles are more stable due to the role of electromagnetic fluctuations. It is shown that for the doped frees…
